Pick up the wrong statement(s).a)The ionisation energies of Xe and dio...
The wrong statements are:

Statement B: In XeF2, lone pairs are occupied in equatorial and axial sp3d hybrid orbitals.
This statement is incorrect because in XeF2, the xenon atom undergoes sp3 hybridization, not sp3d hybridization. The lone pairs of electrons on xenon are located in two of the equatorial positions, resulting in a linear molecular geometry.

Statement D: XeF4 and SF4 are isostructural.
This statement is incorrect because XeF4 and SF4 are not isostructural. XeF4 adopts a square planar molecular geometry with four fluorine atoms surrounding the central xenon atom, while SF4 adopts a seesaw molecular geometry with four atoms (three fluorine and one sulfur) around the central sulfur atom.

Explanation:

Statement A: The ionization energies of Xe and dioxygen are nearly the same.
This statement is correct. The ionization energy is the energy required to remove an electron from an atom or ion. The ionization energy of an element generally increases as you move across a period in the periodic table. Both xenon (Xe) and dioxygen (O2) are located in the same period (period 2) of the periodic table. Although xenon has a higher atomic number than oxygen, the ionization energy of Xe and dioxygen are nearly the same due to the shielding effect of the inner electron shells.

Statement C: XeOF4, XeF6, and XeO3 have the same number of lone pairs on xenon.
This statement is correct. XeOF4, XeF6, and XeO3 all have one lone pair of electrons on the central xenon atom. In XeOF4, the xenon atom is surrounded by four fluorine atoms and one oxygen atom, with the lone pair of electrons on xenon. In XeF6, all six fluorine atoms are bonded to the xenon atom, leaving one lone pair of electrons on xenon. In XeO3, the xenon atom is bonded to three oxygen atoms, with the lone pair of electrons on xenon.

In summary, the incorrect statements are B and D. XeF2 does not have equatorial and axial sp3d hybrid orbitals, and XeF4 and SF4 are not isostructural.

Similar Class 12 Doubts

Read the passage given below and answer the following questions:In transition elements, generally, ions of the same charge in a given series show progressive decrease in radius with increasing atomic number. This is because the new electron enters a d orbital each time the nuclear charge increases by unity. But the radii of the third (5 d) series are virtually the same as those of the corresponding members of the second series. This phenomenon is associated with the intervention of the 4f orbitals which must be filled before the 5d series of elements begin. The filling of 4f before 5d orbital results in a regular decrease in atomic radii called Lanthanoid contraction. In these questions, a statement of assertion followed by a statement of reason is given. Choose the correct answer out of the following choices.Following are the transition metal ions of 3d series: Ti4+, V2+, Mn3+, Cr3+ (Atomic number: Ti = 22, V = 23, Mn = 25, Cr = 24)Assertion (
